[0034] like Figures 1 to 7 As shown, the second shell 12 includes a shell 121, a second space S2 and a plurality of divergent ribs 122; the shell 121 is a circular cover, coaxially combined with the shell 111 of the first shell 11, and includes a second hole 123, and the second hole 123 is axially arranged in the middle of the shell 121; the second space S2 is located in the shell 121 and between the periphery of the shell 121 and the second hole 123; the plurality of divergent ribs 122 are arranged in the second space S2 in the shell 121 and surround the second hole 123, and each of the divergent ribs 122 extends spirally from the periphery of the shell 121 of the second shell 12 toward the second hole 123; a flow channel formed between each adjacent two divergent ribs 122 gradually shrinks from the periphery of the shell 121 toward the second hole 123. The second shell 12 can be provided with a second blending plate 124 corresponding to the first blending plate 116 of the first shell 11 . The second blending plate 124 is also annular, coaxially surrounds the second hole 123 , is coupled to the plurality of divergent ribs 122 , and tapers toward the second hole 123 .
[0035] like Figures 1 to 7As shown, the return member 20 is coaxially arranged in the wheel shell 10 and surrounded by the plurality of driving ribs 112. The return member 20 includes a disk body 21 and a plurality of guide ribs 22; wherein the disk body 21 includes a conical surface, a connecting hole 211 and a plurality of return holes 212, the conical surface faces the second shell 12, the connecting hole 211 is axially arranged in the middle of the disk body 21, and the plurality of return holes 212 are radially arranged in the disk body 21; the plurality of guide ribs 22 surround the connecting hole 211, each of the guide ribs 22 is arranged on the conical surface of the disk body 21 and spirally extends from the periphery of the disk body 21 toward the connecting hole 211; the flow channel formed between each adjacent two of the guide ribs 22 gradually shrinks from the periphery of the disk body 21 toward the connecting hole 211 and is connected with a corresponding one of the return holes 212.
[0036] like Figures 1 to 7 As shown, the turbofan 30 is coaxially arranged in the wheel shell 10, between the first shell 11 and the second shell 12 of the wheel shell 10, and is coaxially fixed to the return member 20; in a preferred embodiment of the present invention, a plurality of bolts are passed through the return member 20 and then screwed to the turbofan 30. The turbofan 30 includes an inner ring 31, an outer ring 32, a plurality of blades 33 and a plurality of through holes 34; the inner ring 31 is annular; the outer ring 32 is annular and coaxially sleeved on the inner ring 31; the plurality of blades 33 surround the inner ring 31, and each of the blades 33 extends from the inner ring 31 to the outer ring 32; a portion of the through holes 34 radially penetrates the inner ring 31 in a circumferential manner and communicates with the second space S2, and another portion of the through holes 34 radially penetrates the inner ring 31 in a circumferential manner and communicates with the return hole 212.
[0037] like Figure 8 As shown, the energy-saving coupling of the present invention further includes a first flange 13, a second flange 14 and a bearing 15, and can be used together with a driving device 50, a driven device 60, an input pipe 70 and two seals 80. The first flange 13 is coaxially coupled to the housing 111 of the first shell 11; the second flange 14 is coaxially coupled to the housing 121 of the second shell 12; the bearing 15 is coaxially disposed in the inner ring 31 of the turbofan 30.
[0038] The driving device 50 includes a motor (not shown), a shaft seat 51 and a support shaft 52. The shaft seat 51 is connected to the second flange 14. The motor is connected to the second flange 14 and can drive the wheel shell 10 to rotate. In practice, the motor can be connected to the second flange 14 by a chain or a belt to drive the second flange 14 laterally and drive the wheel shell 10 to rotate. The free end of the support shaft 52 is hollow and radially penetrated with a plurality of through holes 521. The support shaft 52 penetrates the second flange 14, the second hole 123 of the shell 121 of the second shell 12 and the inner ring 31 of the turbofan 30. The inner ring 31 of the turbofan 30 can directly fix the support shaft 52, so that the turbofan 30 cannot rotate with the wheel shell 10.
[0039] Alternatively, the energy-saving coupling of the present invention can further include a bearing 15 disposed between the inner ring 31 and the support shaft 52. In addition to preventing the turbofan 30 from being unable to rotate with the wheel housing 10, the fluid in the present invention can also be subjected to resistance to prevent the turbofan 30 from being unable to reverse relative to the support shaft 52 and being damaged by force.
[0040] The driven device can include a shaft seat 60, a wheel or a fan. The shaft seat 60 of the driven device is connected to the first flange 13. The wheel or fan of the driven device can be connected to the first flange 13 by a chain or a belt and driven by the wheel housing 10 of the present invention.
[0041] One end of the input pipe 70 is connected to a liquid pump (not shown), which is coaxially coupled to the wheel shell 10 and can rotate with the wheel shell 10. The other end of the input pipe 70 penetrates into the first flange 13, the first hole 113 of the shell 111 of the first shell 11, the connecting hole 211 of the disk 21 of the return member 20, the inner ring 31 of the turbofan 30 and the free end of the support shaft 52.
[0042] One of the sealing members 80 is sleeved on the input pipe 70 and is located between the input pipe 70 and the free end of the support shaft 52 ; the other sealing member 80 is sleeved on the support shaft 52 and is located between the support shaft 52 and the inner ring 31 .
[0043] like Figure 8 and 9 As shown, when the motor drives the wheel housing 10 to rotate, the liquid pump is simultaneously driven to input the filtered liquid into the input pipe 70; the liquid enters the inner ring 31 of the turbine fan 30 through the input pipe 70, and then enters the second space S2 through the portion of the through holes 34 connected to the second space S2; the liquid is guided to the periphery of the shell 121 of the second shell 12 through the multiple divergent ribs 122 in the second space S2 and enters the first space S1; then, the liquid is guided to the middle of the shell 111 of the first shell 11 by the multiple driving ribs 112 in the first space S1.
[0044] Among them, since the guide piece 114 and the driving piece 115 of each driving rib 112 form a pressure angle, the fluid can push against the driving piece 115 of each driving rib 112, and assist the motor to drive the wheel housing 10 to rotate relative to the turbofan 30, and then drive the wheel or fan of the driven device with the wheel housing 10. Therefore, the energy-saving coupling of the present invention can save the energy consumed by the motor, and achieve the purpose of reducing energy consumption.
[0045] Preferably, the bearing 15 can be a brake bearing, so that the turbofan 30 can only rotate in a single direction, which can not only completely prevent the turbofan 30 from rotating with the wheel shell 10, but also prevent the fluid in the present invention from being subjected to resistance and causing the turbofan 30 to be damaged.
[0046] Preferably, a gasket 16 made of Teflon material can be disposed between the return member 20 and the shell 111 of the first shell 11 to prevent the return member 20 and the first shell 11 from being worn.
[0047] like Figure 8 and 9 As shown, after pushing against the driving plate 115 of each driving rib 112, the kinetic energy of the fluid decreases, and the fluid is guided to the connecting hole 211 of the return member 20 through the flow channel formed between each adjacent guide rib 22; the fluid is then introduced into between the inner ring 31 and the outer ring 32 of the turbine fan 30 by the conical surface of the return member 20 and the multiple guide ribs 22, and then guided to the second space S2 through the multiple blades 33 of the turbine fan 30; finally, the fluid is introduced into the first space S1 again through the multiple divergent ribs 122 in the second space S2, and is pushed against the driving plate 115 of each driving rib 112 again.
[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any technician in the relevant technical field, if they do not depart from the scope of the technical solution proposed by the present invention, use the technical content disclosed by the present invention to make partial changes or modifications to the equivalent embodiments, and do not depart from the technical solution content of the present invention, they still fall within the scope of the technical solution of the present invention.
